Why Two Button Quotes Differ by 5x: A Cost Breakdown
Plating thickness, resin grade, tooling ownership, sorting standard and order quantity decide most of a button price — what each driver costs you once the goods are on the line.
Two suppliers quote the same 18L white shirt button at $4 and $18 per gross. The gap is rarely greed. It sits in five places: plating thickness, raw material grade, tooling amortisation, sorting standard and order quantity. This is what each one changes on the production floor, and the six questions that make two quotations comparable.
Start with the unit that hides the difference
Buttons are quoted per gross (144 pieces), per thousand, or per piece, and quotations from Asia often exclude tooling, plating surcharge and export packing. Before comparing anything, convert both to landed cost per thousand pieces, delivered to your warehouse, with tooling amortised over the order.
A quote that looks 40% cheaper usually lands within 10% of the other once tooling, packing and freight are added. The reverse also happens: a quote that looks expensive may include a mould the next order does not pay for again. Comparative unit alone explains a large share of the "five times" stories — and none of the product difference.
The five cost drivers
| Driver | Low quote | Proper quote | What happens in production |
|---|---|---|---|
| Raw material | Mixed regrind, undeclared grade | Virgin resin or urea, grade declared on the PO | Regrind reads dull, yellows within two years, cracks at the hole |
| Plating | 0.05 µm nickel, single layer | 0.15–0.25 µm, copper strike then nickel | Thin plating wears through at the rim in 10–15 industrial washes |
| Tooling | Shared mould, no ownership | Dedicated mould, buyer owns or amortises | Colour and rim profile drift between lots; no exact reorder |
| Sorting / QC | Visual check by eye | AQL 2.5 with batch records | 2–4% defect rate reaches your line and you pay for the rework |
| Quantity | 1,000 pcs, full setup cost per piece | 20,000+ pcs, mould amortised | Small orders carry the entire setup; price per piece never converges |
Plating: the invisible 60% of a metal part
A bright nickel finish at 0.05 µm looks identical to 0.25 µm on the sample table. It stops looking identical after fifteen industrial washes, when the rim turns dull and the base metal shows through. Plating cost scales almost linearly with thickness, so a metal part quoted at half price is usually half the micron.
Ask for the thickness in microns, not a finish name. "Nickel plated" describes a look; "0.2 µm nickel over 0.1 µm copper" describes a part you can reorder, test against ASTM B117 and hold a supplier to. The salt spray hours that go with each thickness are worth fixing in the same conversation.
Material: why regrind is the quiet killer
Moulding buttons generates sprues and rejects, and every factory regrinds some of it. A small percentage is normal. Above roughly 20% regrind the resin loses flow, the colour drifts, and the button becomes brittle at the hole — which is exactly where a two-hole shirt button cracks in the wash.
If the quotation does not declare virgin resin, assume regrind. On a white or pastel button the difference shows up six months on the shelf, not on the sample. For a shell, horn or wood button the equivalent question is grade and thickness of the blank, not regrind — the failure mode there is delamination and chipped rims.
Tooling: who owns the mould, and which parts need one
A button mould runs from a few hundred to a few thousand dollars depending on cavities and engraving. Shared moulds are cheap because the cost is spread across several buyers, and the consequence is that your button is not exactly yours: another buyer's order can shift the colour master or the rim profile.
One distinction saves a lot of quotation confusion: metal and injection-moulded parts need a real mould; natural materials and sheet resin do not. Shell, horn, wood, bamboo, corozo and leather are punched and turned — a new size means a cutting die, which is cheaper and faster. Most shirt buttons are cut from cast sheet, so they carry a cutting die rather than a steel mould. Quoting "mould cost" on a shell button marks the supplier as someone who has not made shell buttons before.
For anything you intend to reorder for more than one season, own the tooling or write an exclusivity clause. It is the cheapest insurance in the whole quotation, and the development timeline shows where the tooling sits in the calendar.
Sorting and QC: the number nobody puts in the quote
A supplier sorting to AQL 2.5 with batch records and a supplier checking by eye can quote the same product and deliver different defect rates. The difference is labour, and labour is in the price.
Ask for the AQL they sort to and whether the result is recorded against the batch number. If they cannot answer, the quality is whatever happened that day. What arrives at your door can then be verified with a goods-in inspection in under an hour.
Quantity: where MOQ pricing actually comes from
Setup cost — mould cleaning, colour change, press warm-up, plating bath preparation — is fixed. Spread over 1,000 pieces it dominates the piece price; spread over 50,000 it disappears. This is why the same button costs $18 and $4 per gross without anyone lying.
Ask for price at three quantities, not one: 5,000, 20,000 and 50,000 pieces. The shape of that curve tells you where the real cost sits, and whether the MOQ you are being offered is commercial or technical.
How to compare two quotations fairly
- Convert both to cost per thousand, delivered, with tooling amortised over twelve months.
- Ask for material grade, plating thickness in microns, and the pull-test result on the production batch.
- Ask which AQL they sort to, and whether records are kept against the batch number.
- Ask for price at three quantity break points, not one.
- Ask who owns the tooling and what happens to it if you move the programme.
- Request a production sample off the line, not a hand-made sample from the mould shop.
Six questions, one page of answers. The quotation that survives them is the cheap one, whatever the number on the paper says.
What our quotes include, and what they do not
Our quotations look mid-market because they carry virgin resin, a declared plating thickness and batch-level test records from our eleven in-house testing machines. On a landed-cost basis across two seasons they usually come out below the cheap quote, because rework, chargebacks and re-sourcing are not free.
If a buyer needs the absolute lowest piece price for a single seasonal run, we will say so and quote that way. What we will not do is quote thin and ship thin.
